The Growth, Production, and Quality of Three Varieties of Shallots (Allium ascalonicum L.) With Hara Sulfur Applications

Introduction

Shallots are one of the most widely cultivated and consumed vegetables in the world, and their cultivation is a significant contributor to the economy of many countries, including Indonesia. However, the growth, production, and quality of shallots can be affected by various factors, including the variety of shallots, soil conditions, and nutrient applications. This study aims to evaluate the growth, production, and quality of three varieties of shallots with variations in the dose of sulfur nutrients.

Methodology

The study was conducted at the Palawija Parent Seed Center, Tanjung Slamat, Deli Serdang Regency, from September to December 2022. The method used was a factorial random block design with two treatment factors. The first factor is a variety of shallots consisting of three types, namely Kramat 1, Maja Cipanas, and Ijo Stone. The second factor is the sulfur dose consisting of four levels, namely 0, 35, 70, and 100 kg/ha.

Results

The results showed a difference in growth, production, quality, and sulfur absorption between Kramat 1 varieties, Maja Cipanas, and Ijo. Significant differences can be seen in the number of leaves and shoots, the weight of the stover, the value of the color space L* and A* from the skin, the anthocyanin content, and the sulfur absorption of the tubers. Ijo stone varieties show results with the lowest number of leaves and shoots, but produce the highest stover weight, the value of the color space A* (red), and the most sulfur absorption. Conversely, Kramat 1 varieties produce the highest wet weight of tubers and are recommended for the study area, especially in the high rainy season.

Discussion

The sulfur dose applied does not have a significant effect on growth, production, quality, dry weight, and sulfur absorption of plants, as well as soil pH and the availability of sulfur after harvest. However, the interaction between varieties and sulfur doses has a significant impact only on the absorption of onion tubers. The highest absorption of tubers is obtained from the green stone variety given the application of 100 kg/ha sulfur.

The Importance of Sulfur in Plant Growth

Sulfur is one of the essential nutrients needed by plants, including shallots. The main function of sulfur in plant growth is as an important component in the process of photosynthesis and protein synthesis. Therefore, this research becomes very relevant, especially for farmers who want to improve the quality and yield of their shallots.

Variety Selection and Nutrient Management

The results obtained from this study indicate that the varieties of shallots have a different response to the sulfur dose. Kramat 1 varieties, which produce tubers with the highest wet weight, show that this variety has a good adaptation to environmental conditions and appropriate nutritional applications. This is important for farmers to choose varieties that are in accordance with local soil and climate conditions to maximize the harvest.

In addition, the results of this study also emphasized the importance of managing proper nutrient doses. Although the application of sulfur does not show a significant effect on some growth parameters, the right dose can increase the absorption of nutrients in the tubers, which contribute to better onion quality.

Conclusion

Overall, this research provides valuable insight for the development of shallots cultivation in Indonesia. By paying attention to the right varieties and managing efficient sulfur nutrient applications, farmers can increase productivity and quality of the onion harvest. This knowledge is very useful in facing the challenges of modern agriculture and ensuring the sustainability of the production of shallots in the future.

Recommendations

Based on the results of this study, the following recommendations can be made:

  1. Variety selection: Farmers should choose varieties that are in accordance with local soil and climate conditions to maximize the harvest.
  2. Nutrient management: Farmers should manage proper nutrient doses to increase the absorption of nutrients in the tubers, which contribute to better onion quality.
  3. Sulfur application: Farmers should apply sulfur at the right dose to increase the absorption of nutrients in the tubers.
  4. Further research: Further research is needed to investigate the effects of other nutrient applications on the growth, production, and quality of shallots.

Limitations of the Study

This study has some limitations, including:

  1. Small sample size: The study was conducted with a small sample size, which may not be representative of the entire population.
  2. Limited treatment factors: The study only considered two treatment factors, namely variety and sulfur dose, which may not be sufficient to capture the complexity of the system.
  3. Limited measurement parameters: The study only measured a limited number of parameters, which may not be sufficient to capture the full range of effects.

Future Research Directions

Future research should aim to:

  1. Investigate the effects of other nutrient applications: Further research is needed to investigate the effects of other nutrient applications on the growth, production, and quality of shallots.
  2. Increase the sample size: Future research should aim to increase the sample size to ensure that the results are representative of the entire population.
  3. Consider more treatment factors: Future research should consider more treatment factors, such as irrigation and fertilization, to capture the complexity of the system.
  4. Measure more parameters: Future research should aim to measure more parameters, such as yield, quality, and nutrient content, to capture the full range of effects.
